From letters to the magazine “Our House”:
“Sometimes I cut potatoes, and inside it is some spots, like rust. Where do they come from, maybe I do not keep potatoes wrong “.
“Why does potatoes turn green?”
We give answers from the same magazine.
Potatoes also “rust”
Most likely, flaws in your potatoes have nothing to do with storage. Brown spots of different sizes and shapes are formed as a result of a lack of phosphorus in the soil where potatoes grow. This disease is called glandular spotting. Therefore, it is necessary to make mineral fertilizers containing this element on the garden or personal plot. Scientists believe that glandular spotting also causes excess in the tuber of iron and aluminum and a lack of calcium, which again depends on the state of the soil. Especially often the disease manifests itself in potatoes that has grown in sandy areas.
For transportation, there is a mesh a bag for potatoes, which will allow you to easily move a large amount of potatoes or any other vegetables or fruits to the storage site.
With improper storage, the so -called gray spotting occurs. It appears both as a result of potato content in very warm rooms, and from bruises, mechanical damage during cleaning and transportation. At first, spots are usually gray, they darken over time, and when cooking potatoes, they become almost black. The nutritional value of such potatoes is very low in it little starch, vitamins, protein.
Gray spotting also occurs with early cleaning of potatoes, a lack of potassium fertilizers in the soil, with dry weather.
Do not put poison in a pan
Gallion of potatoes – the result of the effects of light. Sometimes the potatoes are poorly hilled and part of the tuber protrudes from the ground, sometimes during cleaning the villagers leave potatoes in the bacters for a long time to dry, because wet for storage is not suitable, sometimes it is temporarily stored on the field, then transported to other places.
As a result, under the influence of light in the peel and pulp, the tubers form a poisonous substance – solanine alkaloid. The green potatoes cannot be used for food, neither humans nor animals. Even welded, it is dangerous for homemade living creatures. When using such potatoes, hemiglobin blood is destroyed, which can cause a disease similar to the one that the people are called jaundice.
In much smaller quantities but Solalin is still accumulated in the prophecy of potatoes. Therefore, if it is stored in a warm place and begins to germinate by spring, it is also dangerous to get involved in this, it is also dangerous.
